M M Roper
The effects of sorption phenomena on the interaction between a parasite and its host bacterium have been investigated using anEscherichia coli-bacteriophage-saline sediment system. The sediment contained organic matter and a high proportion...

Paraquat, applied as Gramoxone, to a nonamended sandy loam soil at five times the suggested field application rate (10 lb/A ≈ 115μg/cm(2)) increased the numbers of bacteria, actinomycetes, and fungi during a 14-day incubation at 25°C. Th...
The photobioluminometer, an instrument for the study of ecological factors affecting photosynthesis [0.03%]
用于研究生态因子对光合作用影响的光电化学发光计仪器

Y T Tchan et al.
An instrument for measurement of bioluminescence and photosynthesis is described. It may be used to detect chemicals toxic to luminous bacteria or to measure photosynthetic oxygen production of algae in mixed culture with bacteria. The latt...

G A Zavarzin
Bacterial consumption of CO, a major atmospheric pollutant, has been described in the literature long ago, but often with controversial data. Attempts were made, therefore, to isolate and study a broader spectrum of aerobic CO bacteria in o...
Isolation and characterization of a high molecular weight antibiotic produced by a marine bacterium [0.03%]
一种海洋细菌产生的高分子量抗生素的分离和表征

M Ballester
Many marine bacteria demonstrate antibiotic activity against organisms of terrestrial origin. Low molecular weight antibiotics have been extracted and, in some cases, purified, but few attempts have been made to isolate high molecular weigh...
Simultaneous measurement of phosphorus and carbon uptake in Lake Kinneret by multiple isotopic labeling and differential filtration [0.03%]
同位素标记和不同过滤法同时测定基奈特湖中磷和碳的吸收量

Differential filtration and multiple isotopic labeling were combined to study the uptake of [(14)C]bicarbonate, [(14)C]glucose, and [(32)P]orthophosphate by microplakton in Lake Kinneret, Israel. Short-term (4 hr) uptake experiments showed ...
A simulation model for the effect of predation on bacteria in continuous culture [0.03%]
连续培养中捕食对细菌影响的仿真模型
H W Hunt,C V Cole,D A Klein et al.
H W Hunt et al.
A simulation model was developed for the carbon (C), nitrogen (N), and phosphorus (P) content of bacteria and their medium in a chemostat. Cell components distinguished included the structural component, synthetic machinery, building blocks...
Growth of an estuarinePseudomonas sp. on polychlorinated biphenyl [0.03%]
根瘤芽胞杆菌增殖培养基中心型产气荚膜梭菌的分离与鉴定

G S Sayler
In the course of a study of the microbial degradation of polychlorinated biphenyls (PCB), 16 cultures, representing 5 genera of bacteria, were isolated. APseudomonas sp. was found to degrade mixtures of PCB (Aroclor 1254) and pure isomers, ...
Influence of heavy metal leaf contaminants on the in vitro growth of urban-tree phylloplane-fungi [0.03%]
重金属叶面污染物对城市树叶片植物病原菌体外生长的影响
